On a recent trip to NYC I stayed not far from Financier Patisserie. Every morning I had the supreme pleasure of starting the day with almond croissant and terrific coffee there. I'd recommend it to anyone wanting good pastries, excellent coffee and friendly service. It was a bit on the busy side, but I'm a patient person when people are trying... which they clearly were. The madeleines included were a tasty treat, too.
I'd recommend the hotel, too. It was Club Quarters, on William St. in the financial district. Walking distance from much of what I wanted to see, and close to subway for everything else. The room was a good size, VERY quiet, and a fridge was available on request at no extra charge. Altogether a very pleasant stay.
